Abstract
A laser engraving machine for engraving cylindrical intaglio printing members is arranged to turn the surface of a printing member and engrave it simultaneously. This is not only more efficient but ensures that an accurate relationship is maintained between the engraving head and the turned outer surface of the printing member 3. The engraving machine includes a slide-way 2 extending parallel to the axis of rotation of the printing member 3, a traversing carriage 1 mounted for movement along the slide-way 2 and having a primary sliding carriage 4 mounted on it, and the primary sliding carriage has a secondary sliding carriage 5 mounted on it. The primary and secondary sliding carriages carry a turning tool holder 8 and a laser engraving head 10.
